Question

Identify the domain of the function represented below:y = 3√√x -1+4O y ≥ 4O x ≥ 1Ox>-1Oy ≥ 1

Answer 1

Explanation

We are given the following function:

`y=3√(x-1)+4`

We are required to determine the domain of the given function.

This is achieved thus:

We know that the expression in the root cannot be negative. Therefore, we have:

`\begin{gathered} x-1\geqslant0 \\ x\geqslant0+1 \\ x\geqslant1 \end{gathered}`

Hence, the answer is:

`x\geqslant1`

The second option is correct.
